Sharp pains

Jessica
Hey y'all. I will be 6 weeks tomorrow and today I have been having some on and off sharp pains shooting on my left side near the pelvic area. I work with some Dr.s and one told me it sounds like round ligament pain and nothing to worry about. 
I don't have my 1st ultrasound until 4/6.
Has anyone else experienced this? I'm a FTM and every little thing scares me!
